I went to my first car race in 20 years over the weekend. I took my 7yo son and it was his first race of any kind. We had practiced at Nor Cal a few weeks ago and both of our trucks were pushing with the stock front tires. I bought Soft Enduros for the front of both trucks as they are the recommended tires at the track.

We had 3 qualifiers and an A/B Main. I was managing 13-14 laps while the leaders were getting 18-19. My son was getting 9-10 laps. Not too bad for his first time.

My son's truck had the AE Brushless RTR setup and a stock brushed motor. Mine had the AE FT setup with a Reedy 3300 brushless system. I also had Losi 1 degree hubs on my truck, but I took them off and put them on his truck. Big mistake! I had a couple different sets of rear tires to choose from. I started with SS Enduros and he started with Goosebumps. On my truck the Enduros were terrible. No forward traction or side bite. My truck was fishtailing and spinning out on a regular basis. I swapped rear tires with him so I had the Goosebumps and it was a little better. Then I moved the battery back about 1.5 inches and that helped tone it down a little more, but it was still a handful. I then tried going to Green rear springs and again it helped a little.

We made it through the qualifiers and we were both in the B main. In the last qualifier he broke a front A arm so I scrambled to fix it before the mains. He qualified 18th and I got 15th (out of 18). We were getting our trucks to walk out to the main and he put his antenna up all the way before we left the table. I told him that is a good way to break it and to put it down ASAP. Then he bent the antenna over about 85 degrees about half way up. I quickly straightened it out and taped a 2-56 pushrod to it to keep it from snapping clean off. We got out the the track and his steering trim was screwed so I gave him my truck. We had a good day and he wants to go again.

Today I ordered a couple more sets of the Losi 1 degree rear hubs. I also did some research and realized that the AE drivers are all using a Reedy 5000mah pack that weighs ~10.5 oz while my Orion 3800s weigh 8 oz. I also noticed that most of the setup sheets have between 1.5 and 3oz of weight behind the battery. So I'm going to add 1.25oz on either side of the battery and 1.5oz behind.

Is there anything else I should do to gain forward traction?

Thanks,


Chris

tried more anti squat?

Read towards the end of this thread!

No, But I will add that to my list of things to try. I'm going to try going with the green rear springs, a couple ounces behind the battery and 1 degree hubs. If that doesn't cure it I'll add some anti-squat.

Thanks,


Chris

Go to the Losi 2 degree rear hubs.

They are cheap enough, think you'll really like it.
Makes the truck very forgiving, easy to drive.

Of course only after you find the perfect tires.

Make sure your slipper is adjusted correctly , most of the time it needs to slip some,:nod: do not adjust to tight.....

As you get better you can crank the slipper down and control tire spin with your finger. If your car is light and handling funny try to drop the ride height. Lighter usually means faster.

Which should I get the Losi Xcelorin S 17.5T Combo or Dynamite Fuze SC for my SC10?!?!?! The Fuze runs $115 but also works as a brushed ESC too. The losi is sensored and the LHS has it for not much more than the Fuze but then its intermediate class legal for sure since most places around here say 17.5 but one place allows the FUZE.

I like that both can handle 3s lipo for back yard bashing but I would use 2s for racing.

I've got a couple sets of the 1 degree hubs on the way. I won't run the truck without them again, EVER. If they aren't enough I'll try the 2 degree hubs.

I did adjust the slipper, but as soon as I got off line the truck would spin out. If I loosened it up I couldn't make some of the jumps. It's a pretty tight technical track. On the short back straight they have a tabletop to triple jump. There are also a couple other big jumps that are right after a corner.

Thanks again guys,


Chris

Rarely will a tight slipper give you the best performance .


Most of the time to tight only makes for more wheel spin and even worst, hard off power steering making you saw off the corner's clipping the pipe .:nod:


Adjust so you clear the jumps not a bit tighter is the norm ...:tire:

I only have two threads on the top shaft showing above the slipper nut, using the new yellow pads.....

I use the AE 3degree rear toe in with the thick antisquat piece that is included. A tight clutch gets the motor hotor and lowers run times. But the fun thing is that if I land rear wheels first off a jump and hit the throttle, then I can kinda ride a wheely but maybe its the wind. :D

But you can see in my above post I'm having a hard time deciding on which Brushless combo to get.

yea mine is the same.. I could not believe how far out i had it but it was perfect lol

now I`m just fighting my ball diff. stuck on the bench with a broken screw :( can`t seem to find the right adjustment on it.

im going to instal a new tekin 10.5 in a factory team

am i save with a 18 pinion and a 81 gear?

Anyone hav pics of the holes in the body above / behind the front tires to help keep from catching too much air??

Vent Holes can help if your outdoors , in the wind on a BigOjump ...


Indoors ? Not a big benefit...
